Amazon has them complete with a big bottle to refill the little bottle.
To be completely honest, if that was a really decent pair of headphones it isn't too hard to slap new parts on to it. A decent pair of Sennheisers I would absolutely pick up and clean it. It would be a steal even with the ear STDs.
For 14.99 you could probably do better than those new though. Especially considering they are 18.99 right now with the dock lol https://www.amazon.com/dp/B076P6Q58J/ref=cm_sw_r_apan_glt_i_9X8WH9XS7XEMK7G8MY9A
Someone who is bedridden at home might find need that, it would be a good find for their caregiver. And you can buy them privately, it wasn’t necessarily taken from a hospital

I know you asked this three months ago but I just found this subreddit and have been doomscrolling.
